The Conservation Conundrum

When skimming the websites of environmental organizations, I see virtually no mention of curbing population growth. These groups don't see population as a contributing factor to the world's ailments. The solution, so these environmental websites expound, is conservation: compact fluorescent light bulbs, bicycling, less packaging, bring your own bag when shopping, turn thermostats down.

Sadly, this only buys time; it does not solve the problem. You don't need to be an Einstein to calculate that if we all pitch in and cut energy consumption by, say, 10% per capita, this robust savings will be wiped out as soon as the population grows 10%, which will take about 7 years in the United States. Then energy demand will rise to new records again.


To make matters worse, people don't normally leave their home countries to emigrate to developed nations in order to become "conservers." Many have been attracted by the promise of unlimited everything, including energy.

To make meaningful progress - that is, to actually decrease energy consumption permanently - we must stop population growth. Why aren't we dealing with this issue? If well-intentioned environmental organizations don't recognize this, what hope is there for (short-sighted) politicians?


Conservation is not the answer. But it is important, very important, for it can buy us time to tackle the real issue of population.

How much time will that take? How much time do we have? What's your take?

Darkness and Light and Overpopulation Per Capita


What does NASA's shot of the Earth at night tell us about overpopulation? Check out Europe, Japan, and especially the eastern seaboard of the United States and the Toronto to Montreal corridor in Canada.

Are we that afraid of the dark in the West, or are we just too over-electrified for the size of our populations — and using more power than we deserve to? Sometimes, population issues aren't simply about numbers of people.


Chinese Foreign Minister, Yang Jiechi, points out that his country's per capita emissions of greenhouse gases are still much lower than those of developed countries. "It's like there is one person who eats three slices of bread for breakfast, and there are three people, each of whom eats only one slice. Who should be on a diet?" he asked.

"If per capita energy consumption is viewed in the context of the fundamental principle that people are all born equal, then I don't think some people are justified in talking about the large emissions of China, as if they have the moral high ground."


Hmm. Not sure about that moral high ground, but we sure do have the ground well lit up for us at night.
